Really cool game, I really liked it.
The interaction of the two characters and the lighting is just well made.
if I had to nitpick I'd have the player jump with space instead of just up, and I'd make the platforming feel a bit nicer. Also, the spikes colliders are super unforgiving 😂
But I really like the idea, I tried to do the same lighting effect in my game, although not as good 😂
I'd also have R restart the level and M or any other key bring back the light companion to you. It just feels a bit slow then I have to go get it myself😂
This could even be a nice multiplayer game tbh.
Good job!
